Remove dates from packaging and pick out 24 dates that are whole and plump. Cut an opening into the center but do not cut in half. Sprinkle a few cumin seeds or walnut half into the opening and push into the bottom of the date. Add the piece of cheese and push again to stuff the date. Wrap each date with a half slice of bacon and secure with a soaked toothpick. Place stuffed dates directly on the cooking grate for 10-15 minutes or until bacon is crispy, turning occasionally.
